Abstract: |
The mechanical properties of the symmet rical two-end tapered butadiene/styrene block copolymer initiated by the dilithium initiator were investigated.The results showed that the copolymer possessed remarkable sea-island two-phase structure and two glass transition temperatures;and with the increase of S/B ratio,the physical properties of copolymer changed randomly. |
